Abstract
Description
Technical Field
[0001] This application relates to the field of smart farmland technology, specifically to an integrated intelligent water-saving irrigation and flood control system. Background Technology
[0002] When rainwater cannot drain from farmland during rainy days, it can lead to excessive irrigation. This excess water fills soil pores, displacing air and reducing soil aeration. Prolonged waterlogging can also damage soil structure, causing soil particles to disperse and become compacted after evaporation, hindering root development and growth. This can also lead to root damage and disease outbreaks in crops. Current smart agriculture needs to consider not only water-saving irrigation but also flood prevention. Current agricultural infrastructure for flood prevention is relatively simple, typically relying on simple open and culvert drainage systems, which are limited in function and flexibility.

[0018] For details, please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the overall structure of the intelligent water-saving irrigation and flood control integrated system provided in the embodiments of this application. Figure 2This is a partial structural diagram of the first and second water collection tanks provided in the embodiments of this application. The intelligent water-saving irrigation and flood control integrated system 100 includes multiple irrigation ditches 110 laid in the fields. The irrigation ditches 110 are crisscrossed, and field ridges 120 are formed between adjacent irrigation ditches 110. Drainage pipes 121 are installed at the field ridges 120, and the drainage pipes 121 connect the inner side of the field ridges 120 and the irrigation ditches 110. Each irrigation ditches 110 and the inner side of the field ridges 120 are connected by the drainage pipes 121. Usually, a gate valve is installed at the drainage pipe 121. By opening and closing the gate valve, the connection between the inner side of the field ridges 120 and the irrigation ditches 110 can be switched on or off, thereby realizing the operation of watering the inner side of the field ridges 120 or draining excess water from the field ridges 120. A first water collection tank 130 is connected to the irrigation canal 110. A second water collection tank 140 is located on one side of the first water collection tank 130. The volume of the second water collection tank 140 is larger than that of the first water collection tank 130. The first water collection tank 130 and the second water collection tank 140 are connected by a pressure relief pipe 150. The second water collection tank 140 is used to collect excess rainwater during rainy days, while the first water collection tank 130 is used to receive external irrigation water and divert the irrigation water from the external irrigation water source to the various irrigation canals 110. A pressure relief valve 151 is installed at the pressure relief pipe 150, which can control the connection status between the first water collection tank 130 and the second water collection tank 140. A first water pump 131 is installed on one side of the first water collection tank 130, and a second water pump 141 is installed on one side of the second water collection tank 140. The input end of the first water pump 131 is connected to a water source, and the output end of the first water pump 131 extends into the first water collection tank 130 through a water injection pipe 131a. The water source here can be a well, an irrigation canal 110, or other forms, and should be included as long as it can provide irrigation water. The second water pump 141 is electrically connected to a PLC controller 142. The PLC controller 142 is electrically connected to a first liquid level sensor 143 and a second liquid level sensor 144. Both the first liquid level sensor 143 and the second liquid level sensor 144 are located inside the second water collection tank 140. Typically, the first liquid level sensor 143 and the second liquid level sensor 144 are installed at different heights. They are used to receive the liquid level signal in the second water collection tank 140 and transmit it to the PLC controller 142. The input end of the second water pump 141 is connected to the second water tank through a pipe, and the outlet end of the second water pump 141 extends to the outside of the field through a pipe. The second water pump 141 can discharge excess water in the second water tank to external drainage channels such as flood discharge channels outside the field through the pipe.
[0019] In this embodiment, when irrigation is required, the pressure relief valve 151 at the pressure relief pipe 150 between the first water collection tank 130 and the second water collection tank 140 is closed. The first water pump 131 can introduce external water into the first water collection tank 130. The irrigation water further flows from the first water collection tank 130 to each water channel 110 and then enters the inner side of the field ridge 120 for irrigation. The irrigation water situation at the field ridge 120 is observed. When the irrigation water level at the inner side of the field ridge 120 reaches the set level, the corresponding drainage pipe 121 is blocked. This process is repeated until the inner side of all field ridges 120 is irrigated. Then, the first water pump 131 stops, and the pressure relief valve 151 at the pressure relief pipe 150 is opened. Excess water in the water channel 110 will be discharged into the second water collection tank 140 for storage through the pressure relief pipe 150. During rainy days with heavy rainfall, the drainage pipes 121 at each field ridge 120 are opened. Excess water in the field ridge 120 that is higher than the level of the drainage pipes 121 will pass through the drainage pipes 121, the irrigation ditch 110, the pressure relief pipe 150 of the first collection tank 130, and then enter the second collection tank 140 for storage. As drainage continues, the water level in the second collection tank 140 rises and passes the first level sensor 143 at the highest point. The first level sensor 143 sends an electrical signal to the PLC control box. The PLC control box then controls the second water pump 141 to start, discharging the excess water in the second collection tank 140 to the outside of the farmland. When the water level drops to the second level sensor 144, the second level sensor 144 transmits a signal to the PLC control box, which then controls the second water pump 141 to shut down. The remaining water in the second collection tank 140 is stored and used for later irrigation.
[0020] As can be seen from the above, in this embodiment of the application, by setting up a first water collection tank 130 and a second water collection tank 140, the first water collection tank 130 can accept external irrigation water and guide the irrigation water from the external irrigation water source to each canal 110 to complete the irrigation of the farmland. The second water collection tank 140 can collect excess rainwater from the farmland on rainy days and discharge it to the outside of the farmland through a second water pump 141 to avoid a series of problems such as damage to plant roots caused by excessive irrigation. Furthermore, by setting up a pressure relief pipe 150 and a pressure relief valve 151, the connection between the first water collection tank 130 and the second water collection tank 140 can be flexibly adjusted, so that after the farmland is irrigated, the remaining water in the canal 110 can be returned to the second water collection tank 140 through the pressure relief pipe 150 for storage and backup. In this embodiment, the first liquid level sensor 143 and the second liquid level sensor 144 are set to cooperate with the PLC controller 142 to control the water level in the second water collection tank 140. On rainy days, the water inside the second water collection tank 140 can be drained in time, and sufficient water is retained in the second water collection tank 140 to facilitate subsequent irrigation and save water resources.
[0021] In some embodiments, a third water pump 160 is included. The input end of the third water pump 160 extends through a pipe into the second water collection tank 140, and the output end of the third water pump 160 extends through a pipe into the water channel 110. In this embodiment, by providing the third water pump 160, the third water pump 160 can pump water from the mobile phone in the second water collection tank 140 into the water channel 110 for irrigation.
[0022] In some embodiments, the input end of the first water pump 131 is connected to a three-way valve 131b. The first input end of the three-way valve 131b is connected to a water source, and the second end of the three-way valve 131b extends to the bottom of the second water collection tank 140 through a pipe. In this embodiment, by setting the three-way valve 131b, the first water pump 131 can introduce external water into the irrigation canal 110 inside the farmland for irrigation by controlling the opening and closing of the three-way valve 131b, and can also pump water collected in the second water collection tank 140 into the irrigation canal 110 inside the farmland for irrigation, thus achieving multiple uses with one machine and saving costs.
[0023] In some embodiments, a support frame 145 is provided at one corner of the second collection tank 140, and a crusher 146 is provided on the top of the support frame 145. The orthogonal projection of the discharge end of the crusher 146 is located inside the second collection tank 140. The crusher 146 in this embodiment is used to break up clumps of fertilizer. The crusher 146 here includes a hand-cranked or electric crusher 146, and also includes some devices that crush by vibration. By setting up the crusher 146, the clumps of fertilizer can be broken up and quickly and evenly dissolved in the water of the second collection tank 140. Then, the irrigation water and fertilizer mixture in the second collection tank 140 can be extracted to simultaneously irrigate and fertilize the field.
[0024] In some embodiments, multiple water channels 110 are equipped with barrier filters 170. In this embodiment, by setting up barrier filters 170, impurities in the farmland are prevented from entering the first water collection tank 130, thus avoiding blockage of the entire system.
[0025] In some embodiments, a concrete slope 132 is provided on one side of the first water collection tank 130, and a clamping plate 133 is provided above the concrete slope 132. A leather pad 134 is clamped at the clamping plate 133, and the free end of the leather pad 134 is laid along the direction of the concrete slope 132. The end of the water injection pipe 131a away from the first water pump 131 extends above the leather pad 134. In this embodiment, the above arrangement can effectively prevent the water outlet of the water injection pipe 131a from scouring the first water collection tank 130 and causing damage to the first water collection tank 130.
